New central configurations of the (n+1)-body problem [PDF]

open access: yes, 2018
In this article we study central configurations of the (n+1)-body problem. For the planar (n+1)-body problem we study central configurations performed by ≥2 bodies with equal masses at the vertices of a regular n--gon and one body with null mass. We also

New periodic orbits in the solar sail restricted three body problem [PDF]

open access: yes, 2008
In this paper we consider periodic orbits of a solar sail in the Earth-Sun restricted three-body problem. In particular, we consider orbits which are high above the ecliptic plane, in contrast to the classical Halo orbits about the collinear equilibria ...

The three- and the N-body problem

open access: yes, 2013
We introduce the $N$-body problem of mathematical celestial mechanics, and discuss its astronomical relevance, its simplest solutions inherited from the two-body problem (called homographic motions and, among them, homothetic motions and relative ...

Dual Hierarchy for Gravitational n-body

open access: yes, 2023
The n-body problem is the simulation of pair-wise interactions between n objects. This problem appears in many forms, with the classic example being the modeling of gravitational forces between point masses, necessary for cosmological simulations.

Unchained polygons and the N-body problem [PDF]

open access: yesRegular and Chaotic Dynamics, 2009
The simplest solutions of the N-body problem --symmetric relative equilibria-- are shown to be organizing centers from which stem some recently studied classes of periodic solutions. We focus on the relative equilibrium of the equal-mass regular N-gon, assumed horizontal, and study the families of Lyapunov quasi-periodic solutions bifurcating from them

Comet like periodic orbits in the N-body problem

open access: yes, 1994
Take any nonresonant relative equilibrium solution of the N-body problem. Then there is a periodic solution of the (N + 1)-body problem where N of the particles remain close to the relative equilibrium solution and the remaining particle is close to a ...

On the central configurations of the n-body problem

open access: yes, 2021
We present a brief survey on some classes of central configurations of the n-body problem. We put special emphasis on the central configurations of the 1+n-body problem also called the coorbital satellite problem, and on the nested central configurations ...

Identifying Patterns of Hospitalizations Among Childhood Cancer Survivors: A Population‐Based Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Childhood cancer survivors (CCSs) experience more hospitalizations than the general population. We aimed to identify distinct hospitalization patterns among Queensland CCSs and the associated characteristics. Methods Cases (aged ≤14 years) diagnosed between 1995 and 2019 while residents of Queensland were identified through the ...
